To write data with YODA, you can simply use the write_data()
function of the hoc-language or the put() member
function of the Eventstream class (when called from a
hardcallback).
Once you use this function, the current contents of the eventstream (a
''snapshot'' containing one complete containerevent) is written to
the current output file.
Output to file can be specified
either on YODA's commandline (output option), or interactively with
the File pulldown menu (some minor modifications in the
graphical user interface are required).
The call to put() or write_data() writes the current
contents of the
containerevent to the output file. This includes all subevents, which
may have been added by the hard callback(s) defined. All deleted subevents
will disappear in teh output as well.
Be sure to use the put() member-function or write_data()
function only once for each
containerevent, i.e. from one callback only, else you will get
multiple containerevents with the same contents into the output file.
If you have multiple callbacks, which add or delete subevents
independently you should probably add the put() call into
Eventstream's member function dispatch() only.
